Title: Apparatus for maintining a predetermined temperature in washing liquor
IPC: D06F34/08
Filed: 1971-09-24
Abstract: 1359840 Timed control of electric circuits HOLZER PATENT AG 24 Sept 1971 [25 Sept 1970] 44706/71 Heading G3T In a washing machine an electric heater 3 Fig. 1 for the washing liquid is maintained at a predetermined temperature by a thermostat switch 4 for a longer than normal period, when it is required to effect a biological washing programme i.e. using biological washing agents. The steps of a normal programme are controlled by a programme switch arrangement 1 including a slider 9 driven by a motor 5 via a cam disc 8 and which successively bridges a contact strip 10 to contacts 11 to 18. The periods of energization of motor 5 are relatively short and are dependent upon the width of each contact 11 to 18 and of the bridge slider 9 also upon the motor speed. The extended period is determined by a 'long term' switch arrangement 2 including a slider 30 driven by a motor 7 and a cam disc 8' or alternatively by a motor 6 or by a mechanical timer (not shown). Between each step of the long term switch arrangement 2 is a period of approximately 30 minutes. In operation, as soon as the desired temperature is reached the thermostat switch 4 closes and motor 5 is energized and rotates disc 8 to open a heater switch 3' de-energizing the heater, and to close a switch 36 thereby energizing the motor 7. Simultaneously slider 9 moves to bridge 10 and 12, thereby deenergizing motor 5. The liquid is allowed to cool so that thermostat 4 opens and washing continues until the long term unit slider 30 bridges contacts 20, 21. Thereupon motor 5 is again energized and disc 8 effects movement of slider 9 to bridge contacts 13, 10 so interrupting the supply to motor 5 if the thermostat 4 is still open, and closing heater switch 3' to energize the heater 3. The separate operations follow one another until the long term switch contact 24 is bridged to contact 20 whereupon motor 5 moves the programme switch arrangement to its next operating position and the normal washing programme proceeds.

Abstract: 1,270,870. Electric selective signalling. CHARBONNAGES DE FRANCE. 25 Sept., 1969 [25 Sept., 1968], No. 47281/69. Heading G4H. A device for remotely controlling, e.g. a coal-cutting machine comprises a transmitter having a high carrier frequency generator, a device for modulating the carrier frequency, a first low frequency oscillator normally coupled to the modulator and supplying a frequency which is adjustable over a given range and a second low frequency oscillator which may be temporarily coupled to the modulator in place of the first oscillator and supplying one of a number of discrete frequencies, and a receiver, having a low frequency filter for the adjustable frequency and for each of the discrete modulating frequencies, a short term memory connected between the filter associated with the first oscillator and the corresponding controlled member in the machine and a holding circuit for stopping the machine if no modulating frequency is being received. The discrete low frequencies are used to control discrete operations in the machine and the variable low frequency to control the speed and direction of operation of the machine. The variable frequency is recognized in the receiver by a pair of filters respectively tuned to the highest and lowest frequencies of the range and arranged in parallel so that their response curves intersect at the central frequency of the range. The short term memory is used to maintain the speed of the machine during periods when one of the discrete frequencies is being received. The carrier frequency is modulated by an intermediate circuit generating pulses of a predetermined duration at the frequency of the low modulating frequency employed. A lamp is provided for indicating a drop in the quality of the connection between the transmitter and the receiver. The holding circuit disconnects the power supply to the controlled machine if no modulated frequency is being received.
